    摘要： An optical disk drive apparatus is provided has a reading section (11) which reads the reflection of a laser beam from a disk to produce a read signal, a filter section (14) which filters the read signal with the use of three or more different cutoff frequencies (fl, f2 and f3) upon receiving a control signal from a two or more bits control line, a reproducing section (13) which plays back the read signal filtered by the filter, and a control section (20) which provides the filter with the control signal along the two or more bits control line so that the filtering action with the three or more different cutoff frequencies of the filter is carried out throughout three or more consecutive periods (Tl, T2 and T3) respectively.

    摘要： A plurality of defect management areas (DMA set groups 1 to N) are used in a ring form in such a manner that defect management information of the DMA replaces and is recorded in the next spare area while the DMA is supposed to be still sufficiently rewritable (e.g., currently used DMA sets #1-1 to #4-1 are replaced with the next DMA sets #1-2 to #4-2), and a process returns to a first defect management area again at a time when transition of the defect management information ends up to a last spare area (DMA sets #1-N to #4-N).
